Definitions

  • the invention relates to the field of motor driven cable window operators. Specifically, the invention relates to the reduction in the depth dimension of the window drive unit. This is particularly advantageous owing to the fact that the drive unit and motor combination usually reside within the confines of an automobile door where space for apparatus is limited.
  • the drive unit is inherently bulky owing to the fact that the unit is comprised of several separate subassemblies which are joined to form a drive unit.
  • the various worm gears, worm wheels, and cable drums generally comprise separate elements placed within a larger shell. As such, the completed assemblies take on added dimension and bulk in all directions.
  • a motor drive unit according to the present invention combines several of the previously separate drive unit elements into integral units.
  • a motor drive unit according to the present invention has a reduced depth dimension as compared with state of the art motor drive units owing to the reduced bulk comprised by the combined elements when assembled.
  • the motor drive unit according to the present invention achieves economies in assembly time and resources.
  • a motor drive unit is generally made by the combination of two subassemblies.
  • the first subassembly casing includes the worm drive gear, mounting provisions for an electric motor, and a bearing pin for the worm wheel.
  • the second subassembly casing includes a worm wheel, a cable drum which is connected to and driven by the worm wheel, and mounting provisions for the window lift cable sheaths which guide the cables to the cable drum.
  • the worm wheel and cable drum are combined into a single piece owing to the provision of an extended support sheath on the worm wheel which supports the cable drum.
  • the bearing pin mounted on the first subassembly extends towards and through the center of the worm wheel of the second subassembly so as to support the worm wheel.
  • the end portion of a projecting sleeve of the worm wheel of the second subassembly may also include a set of projecting hook elements which cooperate with corresponding openings located in the casing of the second subassembly so as to hold the worm wheel and the housing of the second subassembly together.
  • motor drive units can be manufactured in a more economical manner.
  • the subassembly can have a reduced depth dimension.
  • the dimensional savings is approximately 4 to 5 mm over a total depth of the motor drive unit of 40+mm. In this manner, motor drive units according to the present invention can be less than 40 mm deep.
  • FIG. 1 is a sectional elevational view of an assembled motor drive unit according to the present invention along section A--A of FIG. 4;
  • FIG. 2 is a cross sectional elevational view of a first motor drive unit subassembly according to the present invention along section A--A of FIG. 4;
  • FIG. 3 is a cross sectional elevational view of a second motor drive unit subassembly according to the present invention along section A--A of FIG. 4;
  • FIG. 4 is a plan view of an assembled motor drive unit according to the present invention.
  • a motor drive unit is comprised of first and second subassemblies, 1 and 2.
  • the first subassembly 1, shown in FIG. 3, includes a housing 3 which accommodates a bearing pin 4 inserted therein.
  • the housing 3 also includes provision for either mounting an electric motor 5 therein, or having the electric motor housing integral therewith.
  • the first subassembly housing also includes a worm gear 5a which transmits the drive from electric motor 5.
  • the second subassembly 2 shown in FIG. 2 includes a housing 6 which includes a passage therein for accommodating the bearing pin 4 of the first subassembly.
  • a worm gear 7 is mounted within the second subassembly, and includes a projecting sleeve member 7a.
  • a cable drum 8 is also mounted within the second subassembly, and is mounted directly on the projecting sleeve 7a of the worm wheel 7. The worm wheel drives the mounted cable drum 8 through the combination of conflicting drive tabs on either or both of the worm wheel and cable drum and damping members 10.
  • the first and second subassemblies are mated together as shown by the arrow marked B on the drawing figures.
  • Bearing pin 4 is inserted into the corresponding hole in the second subassembly to form a rigid connection between the respective assemblies.
  • the subassemblies are also held together by suitable fasteners connected between the plurality of cooperating flanges included on the housings of the respective assemblies.
  • the worm wheel projecting sleeve 7a is equipped with hook elements 7b. Hook elements 7b are inserted into cooperating openings 2a in the second subassembly housing 2. In this manner the combined worm wheel 7 and cable drum 8 are both held in fixed relation, and are also prevented from being pulled from the second subassembly housing 6.
  • FIG. 4 shows a plan view of a motor drive unit according to the present invention. From this view of the unit, the mounting sheaths 11 for the window cables 9 are clearly shown. Also shown are the hook elements 7b of the worm wheel 7 extending through openings 2a in the housing 6 of subassembly 2.
  • the depth dimension of a motor drive unit is shown as dimension CD. Since the electric drive motor 5 is mounted with the first subassembly (on the right in the figure), this portion of the drive unit for purposes of dimension reduction is limited by the shape of the motor 5, i.e., the motor extends a predetermined amount beyond the center axis of the worm drive 5a. Hence, for depth reduction to be accomplished, the dimensional reduction must come from the side of subassembly 2. As such, the present invention drive unit combines the worm wheel and cable drive unit into an integral pair of elements for reduced dimension and assembly ease.
